AWR1642: Implementing the RADAR in Physical environment

Part Number: AWR1642

Hi all,

I am able to connect the AWR1642 BOOST to my PC and run the visualizer on TI cloud platform and find the detected objects on the plot. Now I intent to implement Adaptive Cruise control system. In orde to do it, I just want to use the front 30 degrees as the field of view and consider the objects only within it. How could I access the values of the 2-D points of the objects detected? One method is to use the javascript file of the Visualizer to access the values that are sent for plotting . Is there Any other way through a C/C++ program ? I just want to access the values.  

Thanks

    Hello Amol,

    For data format of Out of Box demo.
    The function MmwDemo_transmitProcessedOutput is touched upon in html help:

    file:///C:/ti/mmwave_sdk_01_00_00_05/packages/ti/demo/xwr14xx/mmw/docs/doxygen/html/main_8c.html#ac3a90335aea273ffb5d4cc76d780a55d

    Transmits detection data over UART.

    The following data is transmitted:

    Header (size = 32bytes), including "Magic word", (size = 8 bytes) and icluding the number of TLV items TLV Items:
    If detectedObjects flag is set, pbjOut structure containing range, doppler, and X,Y,Z location for detected objects, size = sizeof(objOut_t) * number of detected objects
    If logMagRange flag is set, rangeProfile, size = number of range bins * sizeof(uint16_t)
    If noiseProfile flag is set, noiseProfile, size = number of range bins * sizeof(uint16_t)
    If rangeAzimuthHeatMap flag is set, the zero Doppler column of the range cubed matrix, size = number of Rx Azimuth virtual antennas * number of chirps per frame * sizeof(uint32_t)
    If rangeDopplerHeatMap flag is set, the log magnitude range-Doppler matrix, size = number of range bins * number of Doppler bins * sizeof(uint16_t)
    If statsInfo flag is set, the stats information

    Parameters
    Please see if this information helps you obtain the required data structure information.
    Thank you,

    Hi Vaibhav,
    Thank you for the reply. However, I could not find the similar documentation for the xwr16xx directory as that is the one I am concerned with while using the AWR1642 BOOST.

    Hello Amol,
    for AWR1642 you can look at the following doxygen : file:///D:/TI/MMWAVE_SDK_v01.00.00.05/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html
    Look at the output format sent to host and list of detected objects section.

    Regards,
    Vivek
